A function is linear if it is of the form f(x) = mx + c where m and c are constants and a is not zero.
The function implies that an increase of one unit in the input variable, x, always results in an increase of m units in the output.
To determine if a table represents a linear function, check if the differences between consecutive y-values are constant when the x-values increase by a consistent amount. If the change in y is the same for every equal change in x, the function is linear. Additionally, the graph of the function would form a straight line. If either condition is not met, then it does not represent a linear function.
You can determine if a function is linear by examining its graph or its equation. A linear function will produce a straight line when graphed, and its equation can be expressed in the form (y = mx + b), where (m) and (b) are constants. In contrast, a nonlinear function will create a curve or other shapes on the graph, and its equation may involve exponents, products of variables, or other non-linear terms.
To determine if a function is linear or exponential, examine its formula or the relationship between its variables. A linear function can be expressed in the form (y = mx + b), where (m) and (b) are constants, resulting in a constant rate of change. In contrast, an exponential function has the form (y = ab^x), with a variable exponent, indicating that the rate of change increases or decreases multiplicatively. Additionally, plotting the data can help; linear functions produce straight lines, while exponential functions create curves.
Interpolation in general is a way to determine intermediate values from a set of coordinates. Linear interpolation would be to fit a single linear function to the entire set of coordinates. Piecewise linear interpolation would then be to determine intermediate values from the set of coordinates by fitting linear functions between each set of coordinates. Connect-the-dots so to speak.
Your age is a linear function (of time).
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
Assuming the domain is unbounded, the linear function continues to be a linear function to its end.
No. An exponential function is not linear. A very easy way to understand what is and what is not a linear function is in the word, "linear function." A linear function, when graphed, must form a straight line.P.S. The basic formula for any linear function is y=mx+b. No matter what number you put in for the m and b variables, you will always make a linear function.
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
It will just be the gradient of the function, which should be constant in a linear function.

it is impossible for a linear function to not have a y-intercept
As a linear function
Your age is a linear function (of time).
No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.
by seeing if it has a common difference by subtracting the bigger number from the little number and getting the same number over and over and if it does that`s a common difference
It is a continuous function. If the line is a straight line, it is a linear function.
